Abstract: There is provided a material activating device capable of being formed in any one of various shapes and having an improved material activating effect. A material activating device formed by superposing a plurality of polymer film 31 each having one surface coated with a metal film 32, and radioactive layer 33 of a radioactive means has a very small thickness and is very flexible. The metal films 32 are insulated from each other by the electrically insulating polymer films 31 and are spaced from each other by a distance corresponding to the thickness of the polymer films 31. Consequently, the material activating effect of the radioactive rays emitted by the radioactive layer 33 of the radioactive means is enhanced.

Abstract: A material activating device (10) comprises a radioactive layer (11) of a radioactive means that generates radioactive rays for irradiating a material to be activated, and conductive metal layers (12,13) disposed on one side of the radioactive layer (11) and interposed between the radioactive layer (11) and the material to be activated. Radioactive rays emitted by the radioactive means ionizes the material, and the conductive metal layers are charged with electric charges generated when the material is ionized. The conductive metal layers create an electric field and a magnetic field. The material can very efficiently be activated by interaction between the electric and the magnetic field, and the ionized material.
